Ruby Lavender used to have a good life. She and her grandmother, Miss Eula, were inseparable—they even drove the getaway car together for chickens rescued from the slaughterhouse! But this summer, Miss Eula will be in Hawaii, and Ruby's sure it'll be a lonely, empty, horrible season without her. What happens instead? Ruby makes a new friend, saves the school play, writes plenty of letters to her favorite (and only) grandmother . . . and finally stops blaming herself for her grandfather's death.
